| 摘 要： | 在公路下的软弱地层中修建靠近既有桩基的隧洞,是具有难度的近接施工工程问题.使用基于弹塑性增量理论的三维有限元方法,较细致地模拟了输水隧洞接近钻孔桩的施工过程,并考虑了支护混凝土和注浆地层力学参数随龄期的变化.得出了对设计和施工具有重要参考价值的结论.对于类似接近桩基的暗涵工程,具有一定参考价值.

| Abstract: | In this paper,the tunnels construction adjacent to existing pile foundation is studied.Two water diversion tunnels are embedded in soft ground under road.The construction process of tunnels adjacent to bored piles is simulated with the 3-D nonlinear finite element method in details,considering the materials properties change with time.The conclusions and suggestions are valuable for the engineering design,and worthful as references for the similar projects. |
